Application filed May 3, 1901. Serial No. 58,648. (No model.)

To all whom it may acorn.-

Be it known that LNEwToN MONDAY, a citizen of the United States,residing at Plattsburg, in the county of Clinton and State of Missouri,have invented a new and useful Churn, of which the following is aspecification.

The invention relates toimprovements in churns.

The object of the present invention is'to improve the construction ofchurns and to provide a simple, inexpensive, and efficient one capableof being easily operated and adapted to effecta rapid productionofbutter.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is an elevation of a churn constructed inaccordance with this invention. Fig. 2 is a vertical sectional View ofthe same. Fig. 3' is a plan view, on a reduced scale, illustrating theconstruction and arrangement of the sections of the cover. Fig. 4: is adetail perspective view of the rotary dasher. Fig. 5 is a detail Viewillustrating the construction of the groove of the tubular stem.

Like numerals of reference designate corresponding parts in all thefigures of the drawings. 1

1 designates a churn-body, consisting, preferably, of a tub; butanyother suitable receptacle may be employed, and this churnbody isprovided with a suitable spout 2, and

it has a suitable opening, which is normally closed by a suitable plug3, adapted to be Withdrawn to permit the milk to be drawn off after theoperation of churning has been completed.

Within the churn is arranged a series of inclined stationary agitators4, spaced from the sides of the body by blocks or sleeves 5 and adaptedto cause the contents of the churnbody to be agitated when the same comein contact with them, as hereinafter described. The inclined bars, whichhave a'slight curve, are secured at their lower ends to the bottom ofthe churn-body and are connected with the sides by screws 6, which passthrough the sleeves 5, and the latter are located about midway betweenthe ends of the agitatorbars, as clearly illustrated in Fig. 2 of theac: companying drawings.

Cooperating with the stationaryagitators is a rotary dasher 7, securedto a tubular stem 8, which is adj ustably mounted within attubular shaft9 by a set-screw 10 and capable of being raised and lowered to positionthe dasher to the liquid contents of the churnbody. The tubular stem isprovided with an exterior groove or face 11, forming. a seat for andadapted to be engaged by the set-screw to enable the latter to firmlyclamp the stem in the tubular shaft. The tubular shaft, which isdisposed vertically, is journaled in suitable bearings of upper andlower arms 12 and 13 of a standard 14:, and its ends are reduced-to formshoulders to fit against v ceive the shaft, are disposed horizontally,the

upper one being integral with the standard and the lower one beingdetachably secured to the same. The lower portion of the standard isflanged, and the ar1n13 is bifurcated at its inner end to straddle oneof the flanges of the lower portion 15 of the standard and.

is provided at opposite sides of the bifurcation with depending lugs 16,which are secured to the standard by suitable fastening devices 17. Theupper portion of the standard is provided with a vertical opening forthe reception of gears 18 and 19, and itis provided at opposite sides ofthe opening with suitable bearings for the reception of upper andlowerhorizontal shafts 20 and 21. The lower shaft 21 is extendedfrom theinner side of the standard and carries a bevel gear-wheel o 22, whichmeshes with a bevel-pinion 23 of the tubular shaft. The bevel-pinion 23is arranged adjacent to the lower arm-14, and the lower horizontal shaftcarries the pinion or gear 19, which meshes with the upper gear- 5 Wheel18. The gears 18 and 19 are provided with suitable hub extensions, whichare secured by pins or other suitable fastening devices to the upper andlower shafts, as clearly shown in Fig. 1. ed and has a crank-handle 24secured to it, and when the crank-handle is operated the vertical stemis rapidly rotated. The standard is provided at its base with a plate25,

The upper shaft iscxtend- 10a which is secured to the cover of thechurnbody, and this cover is composed of segmental sections 26 and 27.The section 27, upon which the standard is mounted, is engaged atopposite sides of the churn-body by hooks 28, rigidly secured to andextending upward from the said body. The hooks 28 are arranged at theends of the section 27, which is provided between its ends with aprojection 29, which is engaged by a pivoted hook 30. The other section26, which is provided with a central opening to receive the dasher rodor stem, is provided with a projection 31, which is engaged by a hook32, arranged at the outer edge of the section 26. The inner edge of thesection 26 is arranged contiguous to the inner edge of the section 27,and the said section 26 is interlocked with the other section 27 bymeans of cleats 33, secured to the lower face of the section 26 andarranged at an angle to each other and extending beneath the section 27.\Vhen the sections are secured in this manner to the top of the body,they are firmly held in position.

The dasher 7, which consists of a disk, is provided at its lower facewith a central chamher or recess 3%, and it has inwardly-taperinggrooves or recesses 35 located at opposite sides of the chamber andextending outward therefrom. The dasher is also provided at its lowerface with peripheral grooves or recesses 36, extending from the outerends of the tapering recesses or grooves 35. WVhen the dasher is rapidlyrotated, the cream in the central chamber or recess 3t will be thrownoutward by centrifugal. force, and as the' air will be drawn downwardthrough the tubular stem or dasher-rod and will be thrown outward by therotation of the dasher. The cream as it is thrown outward comes incontact with the stationary agitators, and the agitation is therebyrendered more complete. The peripheral recesses or grooves 36, whichform inclined faces, are adapted to impart a downward movement to thecontents of the churn-body, and the agitation of the same is therebyincreased.

It will be seen that the churn is simple and comparatively inexpensivein construction and is capable of rapidly agitating the cream and ofaerating the same, and that it will enable butter to be rapidlyproduced.

What I claim is In a churn, the combination of a rotary dasherconsisting of a disk provided with a central chamber or recess 3landhaving in-' wardly-tapered recesses 35, located at diametricallyopposite points and extending from the periphery of the disk to thecentral cha nber or recess 34, said disk being also provided atdiametrically opposite points with the grooves 36 arranged at theperiphery of the disk, between the said recesses 35 and taperingtherefrom in depth and width and extending from one of the recesses 35to a point opposite the other, and a tubular dasher rod or stem,substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
